8-bit D-type flip-flop with tri-state outputs
The Renesas 74FCT574CTSOG is an 8-bit D-type flip-flop with tri-state, non-inverted outputs triggered on the positive edge. It sits in the 74FCT family, designed for high-speed bus-oriented systems where propagation delay and output drive matter. The single-element, 8-bit architecture matches standard byte-wide data paths in industrial controllers, telecom line cards, and memory interface logic.
5.2 ns propagation delay — timing margin for 50 MHz+ buses
Max propagation delay of 5.2 ns at 5 V with a 50 pF load sets the clock-to-output window.
Industrial temperature range and supply tolerance
Rated for -40°C to 85°C ambient, this part suits factory-floor automation, outdoor telecom cabinets, and engine-bay-adjacent electronics where commercial-grade parts drift out of spec. Supply range of 4.5 V to 5.5 V covers both regulated 5 V rails and the wider tolerance of legacy 5 V systems. Input capacitance of 6 pF is light enough to keep bus loading under control when multiple devices share a common data line.
